v0.2.22-beta: leerling-omgeving (aparte pagina zonder whiteboard)

- Nieuwe tabel `assignments`: een leerkracht koppelt één van haar eigen
  borden aan een klas (standaard) of een individuele leerling (uitzondering,
  voor wie op een ander niveau werkt).
- Geen momentopname: /my/assignment zoekt het bord live op bij de
  leerkracht, dus nieuwe woorden die zij toevoegt komen vanzelf door zodra
  de leerling-pagina opnieuw pollt (elke 20s).
- Leerlingen loggen in op een vereenvoudigde pagina zonder whiteboard/
  tekengereedschap: enkel de toegewezen taal-/rekenwidgets, als vaste
  (niet-sleepbare) kaarten in speelmodus.
- Speelmodus verbergt bewerkfuncties in Ankerwoorden (plaatje kiezen,
  woord typen, kleur wijzigen) en Letterblokken (thema/woordbeheer) -
  overige widgets waren al zuiver speelgericht.
- Elk bord krijgt een stabiel id (board.js) zodat een toewijzing een bord
  blijft vinden ook na hernoemen of herordenen.
- Nieuw tabblad "Toewijzingen" in het beheerpaneel: per klas of leerling
  een eigen bord kiezen, met een expliciete toewijs-stap.
